SOURCE: i have picture but no sound on my 42 inch vizio

If you received a remanufactured board it might be defective,Or did you forget to hook back up the speakers? Sounds dumb but happens alot. Speaker wires get in the way,we disconnect them to look at a board or replace one.Often gets over looked.But I have received several defective boards.Hope this helps. Toddthetvmd

Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Please post back what you find.

SOURCE: vizio vx42L no power will not come on just went

First place to check will be the power supply, look for blown fuse, burnt parts, bad caps with bulging tops. Check for DC voltages, you should have 5, 12, and 24vdc at the power supply DC output connectors.

SOURCE: My Vizio VX42L is flashing like a strobe light.

Mine did the same thing. Remove the stand and back of the tv. Be careful with screen do not lay on hard surface and scratch. When you take the back off you will see a board on the left side and a board on the right side. They are labeled slave and master. Remove the ribbon cables and take board out. There are 2 capacitors on each board (about an inch long). These are probably all bad (ends bulged a little with black stuff on bulged end). Radio shack has them for less than $2.00 each. turn the board over and you can read the size of the capacitor. You need someone who can use solder wick and remove all four capacitors and solder in new ones. Notice how the capacitors are turned. Each one is labeled with a dash for negative. Make sure you bend new capacitor connectors the same and put back in the same way. Put the boards back in the tv and attach all ribbon cables. Put back and stand on. hook up your power and cable box and you are ready to watch tv with no more strobe. Me, my husband, and son did ours last week. I looked up the problem on the internet, husband removed stand & back, son with the steady hand did the soldering. Family project that went well for once.

Is there a fuse


I take it you are referring to the power supply main fuse. It will be on the power supply board next to where the power cable plugs into the board. It should be a T6.3amp fuse if my memory serves me correctly. You will have to take the back cover off the TV set to access the power supply board.

Blue line going vertical on my vizio VX42L


Check all the connection sockets from T'Con board to LCD panel for any loose. Re-seat them. If this do not help you, T'Con board is faulty, and should be replaced.
